Fact Check: Birthmarks NOT Caused By MTHFR Gene Variants, Which Rarely Cause Disease, Are NOT Harmful For Those Receiving Vaccines
Fact Check
Do variants of the MTHFR gene cause disease and increase the likelihood of vaccine reactions? No, that's not true: In rare circumstances, a MTHFR (methylenetetrahydrofolate reductase) gene variant causes neural tube defects in newborn babies. Other times, it can cause elevelated levels of homocysteine, which can lead to blood clots. Otherwise, there are no scientific studies linking MTHFR gene variants,…
